The Guinness Book of British hit singles lists "A Walk in the Black Forest" as having entered the Charts on the 29th July 1965.It peaked at Number 3 and had a chart run of 18 weeks.
I have a vague memory of it being used as the jingle in a beer advert on British TV.May this have been what brought it into the public's awareness in the U.K.? Or did the Ad. come later?
